nwPRovnMn'NT IN -PLows The Schedule-.referred .to in these-Letters Patent-.and making pax-tof the same.

To all tomi/y concern Be it known that I, DAVID A. MANUEL, of Napa city, in the county of Napa, andl State of California,

have invented new, and useful Improvements inPlows ;A and I do hereby declare that the following is fulland `exact description of the same, reference being had to the accompanying drawings, and to the'letters erence marked thereon, of whichof' refe Figure 1 is a side view, showing the landside,

and Figure 2,a top view. l

rIfhis invention is an improvement upon the plow', .patented to D. A. Manuel, May 5, 1868, aud`consists`- in a simple form of mould-board, and a more substan-' tial and conveuientlyfoperating device, for'reversing said mould-board. l

To this.lend,.the mould-board is made one piece, of cast-iron or steel, in the form represented in ig.'2.`

The landside and standard are also made in one piece, in the form` Arepresented in g. 1, a simple arm v uniting the mouldbmd to the landside, and a simple 4lever serving to lock the mould-board in either side of the landside. In the drawingsl A represents the mouldboard, which is made in a nearly diamond-form, with edges a a quite straight, but

'edges a.' a' slightly concave.

This Vboard is, on its rear side, and by means of strong boltsor rivets, b b, fastened firmly to a stout arm, G,

plow-beam, and having a slotfs, extending down through it, in front of the projection, and another, s', running from its front end into the slot s.

E is a lever, with itsl handle extending above the plow-beam, aild pivoted at e, below which point it is attached toa sliding lock-bolt, e.

The forward `end of the landside is made in the angular or cuueiform shape, shown at min iig. 1, and the landside-edge of the mould-board is provided with a downward-projecting iange, fi, 'altA each end, formed tofit accurately over the end fm of the landside, so as to form a close, joint, and so that when in thepositions shown in figs. 1 or 2, the side of the mould-board at 1, and the side of the landside shall together form a straight line. The flange t is thin at the point of contact with the end' of the landside, and whe'the mouldposition, on

board is in the lposition last referred to, the bolt e canl be forced behind the edge of the flange so as to firmly lock the mould-boardA to' the landside ing the handle of the lever back.

. vThe wedge-shaped end ofthe Iandside, entering iut the'fwedge-shaped notch iu' therear'end of the flange i, prevents .the plowpoint t from having; any vertical motion, while the bolt e' and the'landside prevent it from having any lateral motion 'when locked.

The mould-board can be turned on the pivot c, so -as -to throw it on either side of the landside, and can be locked by the device above described equally wel] in 'either position. The form of the mould-board is such that the dimensions, contour, Sac., of the plow are the sainein either case, the only difference being that in the one case it V'isa left-hand, 'and in the other a rghtfhanmploiv.'

rlhe device is exceedingly simple, strong, Aand durable, and can be made at a cost not eiiceeding, 'or' very slightly exceeding, that of the common single mouldboard plow. There is nothing about it liable to clogA or foul in any-way, or to get out of working-order in any kind of soil. Having .thus fully described my invention,

, What I claim, and desire to secure byLetters Pat-v ent of the United States, isv 1. Ihe laudside D, when provided with the vertical -proj ection Df, the pivot c, the slots ss', and the wedge* shaped extremity, all arranged and constructed in a simple piece of cast-metal, substantially as described,

and for the purposes set forth.

2. The mould-board A, when constructed yin the shape described and shown, pivoted, at its middle, to-

thc roar edge of the landside by an arm, C, operating as described, and provided with the flanges '1i-darranged under the `laudside-edge at the endsgallconstructcd and operating in combinationl with the landside ab. ve described, substantially as and for the purposes specied. l

3. The combination ofthe landside and mould-board, above described, with the lever E, pivoted ate, and connected with a sliding lock-bolt e', arranged inside of the landside in a slot or chamber prepared for the purpose, substantially as described, and for-.the purposes set forth.l
